The supporting rod (28) hasa threaded hole (281) defined in the middle portion of the supportingrod (28). A through hole (282) with a diameter smaller than that of thethreaded hole (281) is defined in a bottom of the threaded hole (281),such that a shoulder (not numbered) is formed between the threaded hole(281) and the through hole (282). Multiple cavities (284) are defined inthe supporting rod (28). A groove (283) is defined around eachrespective end of the supporting rod (28).

[0017] The knob (21) is detachably attached to the supporting rod (28).A stub (22) extends downward from the knob (21) and has an outer thread(not numbered) to screw with the threaded hole (281) in the supportingrod (28). A curve cavity (23) is defined in the bottom of the stub (28),and a tab (211) is formed on the top of the knob (21) for the user toconveniently rotate the knob (21).

[0018] The stand rod (25) is rotatably mounted between the supportingrod (28) and the knob (21). The stand rod (25) has a rod body (27)extending through the through hole (282) of the supporting rod (28). Aball (26) is formed on the top of the rod body (27) and is rotatablyreceived between the shoulder in the supporting rod (28) and the curvecavity (23) in the knob (21). A neck (261) with a diameter smaller thanthat of the rod body (27) is formed between the ball (26) and the rodbody (27). In addition, multiple longitudinal channels (271) are definedin the outer periphery of the rod body (27) along an axial direction ofthe rod body (27). In practice, each channel (271) extends to the bottomof the rod body (27).

[0019] The positioning plate (24) is rotatably mounted around the stub(22) on the knob (21) and abuts with the bottom of the knob (21). Athrough hole (242) is defined in the positioning plate (24) for the stub(22) extending through the through hole (242). Two curve edges (240) areformed on opposite sides of the positioning plate (24), and two flatedges (241) are formed on opposite sides of the positioning plate (24).Two protrusions (243) are formed on the bottom of the positioning plate(24).

[0020] The base (30) is detachably attached to the bottom of the stand(20) to support the stand (20). The base (30) has four legs (31)attached to the rod body (27) of the stand rod (25). A T-shaped rail(33) is formed on one end of each respective leg (31) to engage with oneof the channels (271) in the rod body (27). A supporting bar (35) with aU-shaped cross section is pivotally attached to each respective leg(31). An inverse U-shaped recess (311) is defined in the top of eachrespective leg (31) to receive the corresponding one of the supportingrods (35). Two pivotal holes (32) are respectively defined in two sidesof each respective leg (31). Two pivots (351) extend from the innersurface of each respective supporting bar (35) and are respectivelyinserted into the pivotal holes (32) in the corresponding one of thelegs (31) to make the supporting bar (35) be pivotally attached to thecorresponding leg (31).

[0021] The covers (10,101) are rotatably attached to the supporting rod(28) of the stand (20). Each respective cover (10,101) has a skirt (11)extending around the bottom of the cover (10,101) so as to define achamber (12) in the bottom of the cover (10,101). Multiple baffles (notnumbered) are formed on the inner surface of the chamber (12) of eachrespective cover (10,101). The elements of the stand (20) and the base(30) can be securely received in the chambers (12) and held on thebaffles of the cover (10,101) after the stand (20) and the base (30)being disassembled as shown in FIG. 4. A holding tab (17) with a curverecess (not numbered) is formed on each respective cover (10,101) andcorresponds to one of the grooves (283) in the supporting rod (28). Arecess (14) with a curved inner edge is defined in one side of the topof each respective cover (10,101). A depression (15) is defined in thebottom of recess (14) in each respective cover (10,101). Multiple bumps(13) are formed on the top of each respective cover (10,101). Two lockholes (16) are defined in each respective cover (10,101).

[0022] In assembling, the rod body (27) of the stand rod (25) penetratesthrough the through hole (282) in the supporting rod (28), and the ball(26) of the stand rod (25) is supported on the shoulder in thesupporting rod (28). The covers (10,101) are attached on the supportingrod (28) respectively at two sides of the threaded hole (281), and theholding tabs (17) are respectively engaged with the grooves (283) in thesupporting rod (28). A U-shaped rod holder (29) encloses each side ofthe supporting rod (28) and has two ears (291) respectively engagingwith the lock holes (16) in the corresponding one of the covers(10,101). Consequently, the covers (10,101) will be rotatably attachedto the supporting rod (28) with the rod holders (29). The stub (22) onthe knob (21) then extends through the through hole (242) in thepositioning plate (24) and is screwed into the threaded hole (281) inthe supporting rod (28). The legs (31) are attached to channels (271) inthe rod body (27) with the rails (33), such that the stand (20) with thecovers (10,101) can be put on a flat object with the base (30).

[0023] In a first operational embodiment, with reference to FIGS. 1, 2and 5, the knob (21) is slightly released from the threaded hole (281)in the supporting rod (28). The positioning plate (24) is rotatedrelative to the stub (22) of the knob (21) to a position where the curveedges (240) of the positioning plate (24) are respectively received inthe recesses (14) in the covers (10,101). The protrusions (243) on thepositioning plate (24) will be respectively inserted into thedepressions (15) in the covers (10,101). After the knob (21) is screwedonto the positioning rod (28) to a tightened condition, the covers(10,101) are squeezed between the supporting rod (28) and thepositioning plate (24) and are connected to each other through thepositioning plate (24). Two supporting bars (35) corresponding to thesupporting rod (28) are pivotally rotated relative to the correspondinglegs (31) and respectively abut two cavities (284) on the supporting rod(28) with the free ends. Consequently, the user can step on the covers(10,101), and the user can pivotal rotate ankles in two directions withthe supporting rod (28) as an axle as shown in FIG. 5. The ankles of theuser can be exercised with the exerciser. In addition, the bumps (13) onthe covers (10,101) provide a massage effect to the feet of the user.

[0024] In a second operational embodiment, with reference to FIGS. 2 and6, the knob (21) is slightly released from the threaded hole (281) inthe supporting rod (28). The positioning plate (24) is rotated relativeto the stub (22) to a position where the flat edges (241) of thepositioning plate (24) are parallel to the sides of the covers (10,101)and the curve edges (240) are released from the recesses (14). This canrelease the connection between the two covers (10,101). Consequently,the covers (10,101) can pivotally rotate relative to the supporting rod(28) in different directions respectively. Accordingly, the exercisercan be used as a stepping exerciser when the user steps on the covers(10,101).

[0025] With reference to FIG. 7, the supporting bars (35) on the legs(31) are rotated to a position where they abut the corresponding legs(31) and leave the supporting rod (28), so as to release the supportingeffect provided by the supporting bar (35) from the supporting rod (28).Consequently, the supporting rod (28) can universally rotate relative tothe stand rod (25) at the ball (26) as a center, such that the covers(10,101) with the supporting rod (28) can be rotated in a universaldirection relative to the stand rod (25). This can make the user rotateankles in a universal direction.

[0026] With such an exerciser in accordance with the present invention,multiple exercising and training effects are provided, the use of theexerciser is versatile.

[0027] After unscrewing the knob (21) from the threaded hole (281) inthe supporting rod (28), the positioning plate (24) can be taken awayfrom the supporting rod (28). The rails (33) on legs (31) are releasedfrom the channels (271) in the stand rod, and the stand rod (25) can betaken out from the through hole (282) in the supporting rod (28). Todisengage the ears (291) on the rod holders (29) from the lock holes(16) in the covers (10,101), the covers (10,101) can be released fromthe supporting rod (28). Consequently, the exerciser is detached intomultiple separate elements. The elements of the stand (20) and the base(30) can be put into the chambers (12) in the covers (10,101) and beheld by the baffles in the chambers (12) as shown in FIG. 4. To combinethe covers (10,101) with studs (not numbered) and holes (not numbered)formed on the covers (10,101), the covers (10,101) can combine with eachother to receive the stand (20) and base (30). Accordingly, withreference to FIG. 8, the user can easily carry the exerciser toanywhere. The exerciser can be also put into the pocket of clothes orpants for transporting it, such that the exerciser is portable and theuse of the exerciser is convenient.
